Publicly available geological data in the Cooper Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region. Geochemical analysis of gas samples from petroleum in the basin shows various concentrations of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is still unknown. The mineral occurrences are all found in the overlying basins and are small and of little economic significance. The Cooper Basin has some potential for base metal and uranium deposits due to somewhat suitable formation conditions, but the depth of the basin makes exploration and mining difficult and expensive. This also applies to coal, where there are no identified occurrences or resources in the Cooper Basin. However, if some were identified, the depth of the basin would probably make extraction uneconomic, with the potential exception of coal seam gas extraction. CO2 geological storage assessment in the overlying Eromanga Basin suggests that most areas over the Cooper Basin (except over the Weena Trough in the south-west) are prospective for geological storage CO2.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the north Bowen Basin. This data guide illustrates the current understanding of the distribution of these key resource types within the north Bowen Basin region based on trusted information sources. It provides important contextual information on the north Bowen Basin and where additional details on discovered resources can be found. The north Bowen Basin contains 17 metallic mineral deposits, with the majority containing gold. The basin also contains 152 thermal and metallurgical coal deposits. Most coal deposits contain metallurgical coal. This basin contains most of Queensland’s metallurgical coal resources, although many of the deposits supply a mix of thermal and metallurgical coal (Blake et al., 2018). The north Bowen Basin hosts very large coal tonnages, with known black coal resources of approximately 47 billion tonnes. Significant hydrocarbon resources are known to exist in the basin, the majority being coal seam gas (CSG). The basin contains more limited reserves and resources of conventional oil and gas and oil shale. At this time, there are no active or planned CCS projects in the basin.

Publicly available geological data in the Adavale Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains an assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region. Geochemical analysis of gas samples from petroleum boreholes in the basin shows various concentrations of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is still unknown. The Adavale Basin also has the potential for underground hydrogen storage in the Boree Salt. Given the depth of the Boree Salt (wells have intersected the salt at depths below 1800 m) and the high fluid pressure gradient in the basin, the construction of underground salt caverns should include consideration of stability and volume shrinkage. Mineral occurrences are all found in the basins overlying the Adavale region. However, they are small (thousands of tonnes range) and not currently of economic interest. The Adavale Basin has potential for base and precious metal deposits due to suitable formation conditions, but the depth of the basin makes exploration and mining difficult and expensive. There are no identified occurrences or resources of coal in the Adavale Basin. Given the depth of the basin, extraction of any identified coal would probably be uneconomic, with the potential exception of coal seam gas extraction. An assessment of CO2 geological storage also shows prospective storage areas in the Eromanga Basin within the Adavale Basin region in the Namur-Murta and Adori-Westbourne play intervals.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the Galilee Basin region. This data guide illustrates the current understanding of the distribution of these key resource types within the Galilee Basin region based on trusted information sources. It provides important contextual information on the Galilee Basin and where additional details on discovered resources can be found. The Galilee Basin region contains 6 known metallic mineral deposits, with most of these containing the critical mineral vanadium. There are 17 coal deposits found in the basin containing thermal and metallurgical coal. The primary form of coal in the deposits is thermal coal. The Galilee Basin hosts large coal tonnages, with known black coal resources of approximately 33 billion tonnes. The Galilee Basin and overlying basins are known to contain significant hydrocarbon resources. The majority of the known hydrocarbon resources are found in the Julia Creek oil shale deposits located in the Eromanga Basin above the Galilee Basin. Moderate coal seam gas (CSG) resources have also been identified in the basin; however, conventional gas resources are more limited. At this time, there are no active or planned Carbon Capture and Storage (CCS) projects in the basin.

Publicly available geological data in the Galilee Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region. The mineral occurrences are mostly found in the overlying basins, and they are often small and of little economic significance. There are some exceptions, such as the Lilyvale vanadium deposit found in the northern Galilee region, in the overlying Eromanga Basin. The Galilee Basin has limited potential for uranium and precious metal deposits due to relative lack of suitable formation conditions, but the depth of much of the basin makes exploration and mining difficult and expensive. There are some large coal measures found in the Galilee Basin, with 17 deposits in the Galilee and overlying Eromanga basins, containing about 38 billion tonnes of black coal. An assessment of geological storage of CO2 potential suggests the Galilee Basin Betts Creek - Rewan Play is the most prospective for storing CO2, with the highest potential around the central basin region. There are no reports of natural hydrogen in the Galilee Basin.

<div>The soil gas database table contains publicly available results from Geoscience Australia's organic geochemistry (ORGCHEM) schema and supporting oracle databases for gas analyses undertaken by Geoscience Australia's laboratory on soil samples taken from shallow (down to 1 m below the surface) percussion holes. Data includes the percussion hole field site location, sample depth, analytical methods and other relevant metadata, as well as the molecular and isotopic compositions of the soil gas with air included in the reported results. Acquisition of the molecular compounds are by gas chromatography (GC) and the isotopic ratios by gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS).

Publicly available geological data in the north Bowen Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region. Geochemical analyses of gas samples from petroleum, coal and coal seam gas boreholes in the basin show traces of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is unknown. Numerous mineral occurrences are found in the basin. Most contain gold, which historically has often been mined. Most occurrences are small, with some exceptions, such as Cracow, Golden Plateau, Kauffman’s Prospect and Miclere gold deposits. The north Bowen Basin has potential for epithermal gold-silver and gold-copper deposits in the deeper formations, but the depth of much of the basin makes exploration and mining difficult and expensive. There is also potential for sandstone-hosted uranium and paleoplacer gold deposits in the upper coal-bearing formations, such as what is seen in the Miclere area. The north Bowen Basin has a significant quantity of coal, with 152 deposits found in the basin, totalling about 47 billion tonnes of black coal. The results of CO2 geological storage assessment of 3 play intervals in the north Bowen Basin suggest there is low storage potential within the basin.
